Abstract (en)
[origin: WO2010102728A1] The invention relates to a drive authorization system for an electric drive (10), comprising a predetermined number of field coils (11, 12, 13, 14, 15, 16) and a rotatably movable element (17), wherein an analysis and control unit (20) for the operation of the electric drive (10) determines a current position of the movable element (17) from multiple position information which can be provided by a predetermined number of rotation angle sensors (21, 22, 23, 24, 25, 26). According to the invention, positions (21.1, 22.1, 23.1, 24.1, 25.1, 26.1) and/or a number of the active rotation angle sensors (21, 22, 23, 24, 25, 26) are implemented in encoded manner for realizing an electronic immobilizing function, wherein the analysis and control unit (20) decodes the encoded position information of the active rotation angle sensors (21, 22, 23, 24, 25, 26) for determining the current position of the movable element (17), wherein the operation of the electric drive (10) is only possible after the successful decoding of the position information.
